The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) received 36,000 comments on proposed backdoor bump stock gun control, and
85 percent of those who commented said they opposed it.
On December 22, 2017, Breitbart News
reported that the ATF was taking comment on their intention to change the definition of “machinegun” so as to include a firearm that is not a “machinegun” as well. This would allow them to use the National Firearms Act (1934) to regulate machineguns and non-machineguns in the same way, which would allow them to treat simple firearm accessories and actual firearm conversion devices the same.
